The purpose of this study was to investigate the performance of dental infection control. This survey was performed on 158 of the dental hygienist in certain areas. The research was performed using a self-reported questionnaire and interview method from June to July, 2014. The collected data was analyzed by PASW Statistics ver. 18.0. Guideline of infection management, infection controller, regular infection control training, Sterilization of the handpiece/per head resulted 57~74% for dental hospital. It was higher than 13~20% for dental clinics (p<0.05). Infection control guidelines and vaccination recognition of dental were more performed in dental hospital. Patient's hand hygiene performed, tooth brushing before treatment, cross infection educational experience was less than 20%, research cooperation of medical history was over 90% (p<0.05). Performing rate of the dental hospital workers were investigated higher in protective personal devices, infection control of treatment room. A correlation analysis about institutional support, infection control of dental hygienists, patients with infection control cooperation showed a positive correlation statistically significant. Infection control can be enhanced when the medical staff, the patient, the organization combined cognitive and practice. Dental hygienist is required to recognize and practice the infection control guidelines through continuing education.

Objectives: The objective of the study was to infection control by analyzing the influence of working environment on infection control activities in the dental hygienists. Methods: The cross-sectional study was based on a survey on a total of 377 dental hygienists working in dental settings. Multiple linear regression analysis was performed to examine the relationship of general characteristics and infection control activities. All statistical analyses were performed using the SPSS for Windows version 20.0, and p<0.05 was considered to be significant. Results: Predictive powers(=Adjusted $R^2$ of the investigated factors such as operation room, sterilization disinfection laundry, dental unit waterline, staff individual, infection control system, personal protective equipment, medical waste, hand hygiene, oral surgical procedures, clinical contact surfaces were adjusted $R^2=0.394$, 0.306, 0.277, 0.244, 0.241, 0.177, 0.165,, 0.154, 0.134, 0.124 respectively. Conclusions: In order to enhance infection control activities, the program development and implementation for the aseptic procedure is very important.

Objectives : The purpose of this study was to minimize cross infection that can take place within dental office, to make dental workers recognize importance of infection management, and to improve dental-care environment that is exposed to infection. Methods : It conducted the self-reported questionnaire survey on the practice of wearing PPE(personal protective equipment) from April 1, 2008 to May 30 targeting 180 dental workers who are working for dental offices where are located in Jeonnam region. Results : 1. As for research subjects' general characteristics, age was the largest in under 29 years old with 75.0%. It was surveyed to be large in over 5 years(56.1%) for working career, in a city(83.3%) for working region, and in having licence of dental hygienist(75.0%). 2. As a result of surveying the practice of wearing PPE, wearing mask given dental care was surveyed to have the highest practice level with 75.6%. Wearing protective glasses showed the lowest practice ratio with 23.3%. 3. As a result of surveying the difference in the practice of wearing PPE according to general characteristics, the difference according to the working region was surveyed to be the greatest. Conclusions : As the above result, the education of infection management for dental workers needs to be performed continuously even after curriculum of school. Even the in-service education on infection management needs to be vitalized. Also, the necessity was examined for always recognizing and practicing importance of infection by using a method of publishing newsletter via post to dental clinics where are located in rural area, with considering regional deviation.

The purpose of the study was to provide the basic for the prevention of infection control by analyzing the level of recognition and practice of dental hygiene students. It is important for dental clinic staffs to know and practice infection control measures in favor of effective infection control. Thus, this study conducted an one-month questionnaire survey (during October 2008) for dental hygiene students who ever experienced in 16-week clinical practice, and analyzed total 206 questionnaire forms as collected from them, so that it could determine potential associations between their recognition and practice of infection control and thereby suggest an efficient solution for infection control in dental hygiene. 1. It was found that our students' recognition about infection control averaged $4.49{\pm}.58$ points on the whole, and they were best aware of instrumental disinfection and sterilization among other measures, which was followed by hand washing, extirpation control, post-sterilization management, personal protective outfit and instrumental surface maintenance respectively. 2. It was found that our students' practice of infection control averaged $3.85{\pm}.57$ points on the whole, and they practiced hand washing most actively among other measures, which was followed by extirpation control, post-sterilization management, instrumental disinfection and sterilization, personal protective outfit and instrumental surface maintenance respectively. 3. It was found that our students scored higher mean points in recognition about every measure of infection control than those in practice (t=15.676, p=0.000). Particularly, it was notable that there were significant differences between their mean points in recognition and practice of some infection control measures, such as instrumental surface maintenance (t=15.361, p=0.000), personal protective outfit (t=15.245, p=0.000) and instrumental disinfection and sterilization (t=11.169, p=0.000). But there was least significant difference between mean points in recognition and practice of hand washing (t=5.460, p=0.000). 4. For potential associations between recognition and practice of infection control, it was found that higher recognition was in significantly positive associations with higher practice in every measure of infection control (r=.478, p=.000), such as extirpation control (r=.630, p=.000), instrumental disinfection and sterilization (r=.477, p=.000) and post-sterilization management (r=.433, p=.000). 5. It was found that there were differences in our students' recognition depending upon availability of infection control guideline (t=4.587, p=.011), and there were significant differences in practice depending on necessity of infection control education on a statistical basis (t=2.229, p=.027). Overall, it is found that our dental hygiene students are very likely to practice hand washing and extirpation control, because both of these measures are relatively easy to practice or are considered legally binding.

Infection control is critical to good dental practice. To this end, it is essential that the practitioner not only understand the concepts involved in the development and applications of antimicrobial(physical and chemical) agents but also know how to use them properly in the dental operatory. Practical applications of infection control are more fully described in several of the suggested references.
